Properties

code

code: string

Standard code name of the CRS passed into WMS services (e.g. 'EPSG:3857').

projection

projection: IProjection

Projection that this CRS uses.

transformation

transformation: Transformation

Transformation that this CRS uses to turn projected coordinates into screen coordinates for a particular tile service.

Methods

getSize

getSize(zoom: number): Point

- Defined in src/typings/leaflet/leaflet.d.ts:1152
Returns the size of the world in pixels for a particular zoom.

Parameters
- zoom: number
Returns Point

latLngToPoint

latLngToPoint(latlng: LatLng, zoom: number): Point

- Defined in src/typings/leaflet/leaflet.d.ts:1128
Projects geographical coordinates on a given zoom into pixel coordinates.

Parameters
- latlng: LatLng
- zoom: number
Returns Point

pointToLatLng

pointToLatLng(point: Point, zoom: number): LatLng

- Defined in src/typings/leaflet/leaflet.d.ts:1134
The inverse of latLngToPoint. Projects pixel coordinates on a given zoom into geographical coordinates.

Parameters
- point: Point
- zoom: number
Returns LatLng

project

project(latlng: LatLng): Point

- Defined in src/typings/leaflet/leaflet.d.ts:1140
Projects geographical coordinates into coordinates in units accepted for this CRS (e.g. meters for EPSG:3857, for passing it to WMS services).

Parameters
- latlng: LatLng
Returns Point

scale

scale(zoom: number): number

- Defined in src/typings/leaflet/leaflet.d.ts:1147
Returns the scale used when transforming projected coordinates into pixel coordinates for a particular zoom. For example, it returns 256 * 2^zoom for Mercator-based CRS.

Parameters
- zoom: number
Returns number
